Some people live on a different planet.. The last social event I did (last night) I took the train to their house which cost me $5 return, and we went out to eat at a Japanese restaurant where I got a Chicken Katsu for $17AUD. This social event cost me not much more than if I had sat at home and ate dinner normally.

As others have mentioned, wealth inequality, even comparing the top 10% to the 30% paints a very different picture.
